Re: Secondary fuel pump dead?
Yes. I split the holder down one side. Secured with tie wraps.

Re: Fuel pump bypass Switches
I have one of the "emergency" harnesses that the Wazoo group makes. Plugs in between the tank and tank harness when needed. Switches primary pup power to the secondary pump.

Re: Secondary fuel pump dead?
I got the high flow pumps as I'm pushing around 560 crank hp.

Re: WTB: Secondary Port Solenoid
Maybe Pete has some. He's been clearing out his collection of parts on Facebook.

Re: 1992 Upper Radiator Shroud Removal
I didn't have an issue with mine. Make sure the intake assembly is in the correct orientation. Hose should just slip on.

Re: 1992 Upper Radiator Shroud Removal
I don't remember how I did it since it was several years ago. Probably the same way you managed it. Getting the spacers in will be another challenge.

Re: 1992 Upper Radiator Shroud Removal
For me, it was a lot of trial & error, just hoping I wouldn't break anything. However you get it out, remember because it goes back the same way.

Re: 1992 Upper Radiator Shroud Removal
Once all the bolts are out, the next challenge will be getting it out from under the AC and oil cooler lines.

Re: 1992 Upper Radiator Shroud Removal
Yes. Very hard to get them. I used a small 8mm wrench for the ones I couldn't get with a 1/4 " drive ratchet, extension and universal joint.

Re: 1992 Upper Radiator Shroud Removal
If I remember correctly, it was just a couple of bolts. I disconnected everything from the top. Remove the hoses from the pump. It doesn't need to move far.

Re: 1992 Upper Radiator Shroud Removal
Did you get the 3 on each side? 8mm head.
Also 2 on each side down by the frame rails.

Re: Oil leak
Most likely the crank sensor, but there is oil a bit higher on the block. Maybe being blown around?
When Mark built the 415, he had a leak at the crank sensor as well. Haven't had a leak anywhere...
